Fri, 11/20/2009 - 17:00
No eruptive activity has been detected at volcanoes in Alaska this week. Because there are no volcanoes at elevated color codes or alert levels, AVO has suspended its daily reporting procedures and is not issuing its usual daily status reports.
Fri, 11/20/2009 - 17:00
AVO can no longer seismically monitor the following volcanoes because of seismic station outages. As a result, AVO is unable to (1) assess whether these volcanoes may be building towards an eruption and (2) quickly confirm or dismiss reports of activity at these volcanoes.

On Monday, the Alaska Volcano Observatory downgraded Shishaldin Volcano to aviation color code GREEN and alert level NORMAL. Recent clear satellite views of Shishaldin show no activity at the volcano, with the last thermal anomaly observed on August 16. While seismicity remains variable, it is still within background levels for this volcano.
In addition, Cleveland Volcano was lowered to aviation code and alert level UNASSIGNED. No eruptive activity has been observed at Cleveland since ...
Fri, 10/23/2009 - 17:00
No Alaska volcanoes are currently at elevated Aviation Color Code or Volcano Alert Level. Daily Status Reports will be discontinued after today until the situation changes. The status of Alaska volcanoes will continue to be reported in the Weekly Updates.
Fri, 10/23/2009 - 17:00
No eruptive activity has been observed at Cleveland since the brief eruption at approximately 2330 AKDT October 2 (0730 UTC October 3), and recent clear nighttime satellite views showed no signs of activity. Therefore, AVO is reducing the Aviation Color Code to UNASSIGNED and the Volcano Alert Level to UNASSIGNED.
The lack of a real-time seismic network at Cleveland means that AVO is unable to track local earthquake activity related to volcanic unrest. Unrest at Cleveland is frequent, and ...

Recent clear satellite views of Shishaldin show no activity at the volcano, with the last thermal anomaly observed on August 16. While seismicity remains variable, it is still within background levels for this volcano. Shishaldin has had intermittent periods of unrest since January 2009, typically accompanied by thermal anomalies and increased steam emissions. The apparent waning of this activity over the past two months prompts AVO to reduce the Aviation Color Code to GREEN and the Volcano ...

No eruptive activity has been observed at Cleveland since the brief eruption at approximately 2330 AKDT October 2 (0730 UTC October 3).
Recent clear nighttime satellite views of Cleveland showed no signs of activity.
The lack of a real-time seismic network at Cleveland means that AVO is unable to track local earthquake activity related to volcanic unrest. Short-lived explosions with ash plumes that could exceed 20,000 ft above sea level can occur without warning and may go undetected on ...
Fri, 10/23/2009 - 17:00
Seismic activity at Shishaldin remains low. The Webcam has been inoperable since October 10, and recent satellite views have been mostly obscured by clouds.
